Application filed January I0. 1906.` Serial No. 295.403.

invented certain new and useful Improvements in`Side Bearings' for Railway-Cars; and I doher'eby declare thai-the fo lowing is a full7 clear, and exact description thereof,

, reference being had to the accompanying drawin s,` and lto the letters of reference 'marke thereon, which form a part of this specification.

This invention relates to improvements in side-bearings for railway cars of that kind adapted to be interposed between the carbolster andthe truck .of a railway car, in suchmanner as to afford an antifriction bearing between said bolster' and truck upon the occasion of relative angular movement of the truck 'and car, as when `the car is passing,

around a curve.' l The `invention consists in the matters hereinafter set forth and more particularly pointed out in the appended claims.

'Among the objects of my invention is to provide a strong and durable bearing of the character specified, one which may be readily assembled and as readily taken apart for the purpose of repairing or replacing any of the parts thereof, and to provide a bearmg possessing these qualities which maybe economically manufactured.

In the drawm s:-Figure 1 is a side elevaL tion of a roller earingmade in accordance with my invention, showing a portion of the car bolster and the truck associated therewith. Fig, 2is a longitudinal vertical sectionthereof. Fig. 3` isa transverse section,

taken on line 3-3 of Fig.'2 showing the bearing roller in elevation. Fig. 4 1s a transversesection, taken on line Jr-,4 of Fig. 2.

x y. Fig. 5 is a perspective view of the 'main cast- 'mounted t 45 4and open at its bottom to permit'the roller to roject therethrough for contact W1th a lower' "hearing surface. The, two-part casing or shell 'embraces -a lower member 1n which the rolleris mounted to have free movement both lower bearin horizontally land vertically, and an upper member fitted to and attached to the lower member and provided with fastening devices by which the bearing is attached to the bolster. In the construction herein shown, the lower member of the shell or casing is open at its top land the roller is introduced to the roller chamber of said member throu h the open top thereof, and the up er mem er of t e shell is designed to provl e a wall which closes the open top of said lower member. The lower member of the shell is provided with tracks which support the roller whenv the latter is below and free from the up er bearingsurface, whereby the roller ,is at t `s time free to adjust itself longitudinally of thel shell to present new points of contact to the bearing surfaces upon their next contact, and the roller is movable vertically relativel to the track so as to befree from thetracli when the roller engages both the upper and surfaces. .One or more rollers may bc emp oye'd in each bearing. In the resent instance I have shown two, and have illustrated a form of casinor or shell which admits of the use of two rol ers,while maintainin them independent in their action.

As s own in the drawings, 6 designates the car bolster to which my bearing is attached, and 7 an u wardly facing bearing plate iixed to' the truc underneath.

8 designates my improved side bearing, as a whole. It comprises a suitable casing or shell containingone or more bearing rollers 9, two being herein shown, which are adapted for bearing contact with the lower bearing `plate 7, and an upper bearing plate l0 in the top of the casing or shell. The casing or shell is composed of two parts, a lower member 11 that receives'the rollers 9 and an upper member 12 that is attached to the lower member -and is itself provided with apertured lugs 13 byV which the bearing is attached to the car bolster.

As herein shown, the lower member of the shell or casing consists of a generally rectangular, hollow casting formed to constitute' Said two chambers to receive the rollers 9.

chambers are se arated bv a transverse par. g

tition 14 where the rollers operate independentlyin their chambers and are at all times free from contact ith each other.4

, its bottom and top to permit r of said` rollers,

made *integral with each other, and is open at olling contact through said openings with The theupper and lower bearing surfaces. upper bearing d rate froml theupper and. lower members of the shell. -Said bearing plate rests upon the top of said upper member and is conned between the upper and lower members.` The side walls of the casing are provided near their lower margins with horizontal, inwardly directed tracks 17, andthe rollers 9,arepro vided with oppositely or end bearings 18 adapted to engage said tracks. Said .tracks are located at such distance from the -upper bearing plate 10 that when the rollers are supported by their trunnions on the tracks17, the bearing faces or treads of the rollers are free from lthe upper bearing surface, orthe'plate 10; and said Arollers have vertical movement in thecasing.

' relatively to the tracks so that when the rollers are engaged with the upper and lower bearings surfaces, and weight is, therefore,

transmitted through the bearing rollers from "the-upper to the lower bearings surfaces, the

trunnions arefree from said tracks 17. The side walls of the lower member of the casing or shell are provided at their upper margins with inwardly extending ledges or Hanges 19 and, when the rollers are introduced inte their chambers 'through the open top of said lower member, vprovide notches 20 through which the trunnlons of the roller passesvwhen 'the roller is` inserted in place.

The/upper member of the casing comprises a top wall 21 between which and end walls of the lower member.

and the top of the lower member the bearing l plate 10is confined, side walls 22 and end walls 23, said side and end walls fitting iny overlapping relation closely outside'the side The two parts of the casing or shell thus formed are 'attached together by means of a bolt or rivet 24 that extends transversely through lugs 25, formed on the lower margins of the Iside-Walls of the upper member ci? the shell, and through the transverse partition wall 14 before referred to. d

The upper bearing plate ,10 rests upon, the end walls and the fianges or extensions 19 of the side walls of the lower member of the casing is held from lateral displacement by means of lugs 28, 28 rising from the upper side of said lower member of the casing. 'i he ysaid lugs are made of .less depth than the thickness of the bearing-plate, whereby the clamping engagement' of the upper wall of the upper member of the shell is exerted upon said bearing plate to hold or confine the same xedly between the upper andlower mem-v bers of the casing. The partition wall 14 of the lowery member ofthe casing which divides t-liefsamefintd two roller chambers is herein shown 'as' provided on its upper margin with increases the extent plate is shown as made sepa-A extending trunnions said flanges are cut away to divergent extensions or flanges 29, 29 .which of the bearingsurface for the upper bearing plate.

By reason of the two-part construction ofv the casing or shell for the rollers 9, the bearing is capable of being readily assembled and applied to the bolster and may be also readv ily taken apart for the purpose of repair or replacement ofvany of the parts thereof. The overlapping arrangement of the upper and lower members of the casing or shell produces an exceedingly strong and durable construction. The casing is Afurther greatly strengthened by the presence of the rivet or bolt 24 which extends'transversely vtherethrough and rigidly connects the side wall thereof, this construction preventing spread-v ing of the side walls of the casing. Such advantage is found also in a casing having sin-v i of the roller into In co-pending applications filed by me on "f i February 11th, 1907, Serial Numbers 356,77 9 and 356,780 are shown side bearings wherein the rollers are confined in the 'casings by wear-plates, but in said. latter constructions the casing in which is formedthe roller chamber vconsists of an integral casting-.and the parts are so arranged that the wear plate .may be inserted into the roller chamber through' the' openings .through which said II claim as my invention vroller extends for contact with an. exterior bearing surface.
